PEARL J, WENTWORTH, OF FORT THOMAS, KENTUCKY.

METHOD OR PROCESS OF LAYING AND SECURING SOLES TO UPPERS.

Application filed June 8, 1917.

To all whom it may concern Be it known that I, PEARL J. VVnN'rwoRTH, acitizen of the United States, a resident of Fort Thomas, in the countyof Campbell and State of Kentucky, have invented new and usefulImprovements in Methods or Processes of Laying and Securing Soles toUppers, of which the follow ing is a specification.

My invention relates to improvements in the method or process of layingand securing soles to uppers, the principal object being a simple andeffective process of pressing an outsole of an upper with an adhesivetherebetween, the pressure being continued a sufficient length of timeto enable the adhesive to set.

Another object is the provision of such a process wherein an elasticband is utilized by wrapping the same about the sole and upper so as toafford a continuous pressure over the sole so as to accomplish theleveling of the same, and also to hold it against the upper until theadhesive, which has been placed therebetween, sets.

To the accomplishment of the foregoing and such other objects as mayhereinafter appear, my invention consists in the various steps andoperations hereinafter described, and thensought to be defined in theappended claims, reference being had to the accompanying drawing forminga part hereof, and which illustrates the various steps or stages of mynew process or method, it being understood that these may be varied inpractice within the scope of the claims without digressing from myinventive idea.

In the drawings,

Figure 1 represents a bottom perspective view of a lasted upper, withthe heel and sole applied thereto, and being held in position by meansof an elastic band, which has been wrapped therearound;

Fig. 2 is a similar view of a slightly dif ferent form of shoe, and

Fig. 3 is a similar view to Fig. 2, the elastic band only beingpartially wrapped around the shoe.

In carrying out my process, I utilize the last 1 on which the upper 2 islasted. This upper may be of any standard form and construction. On thislasted upper is applied the outsole 3 which may or may not have the heel4, depending upon the character of shoe being made. This outsole 3Specification of Letters Patent.

is placed in position on top of the lasted upper with a suitable coatingof adhesive or adhesive material, placed therebetween.

In order to permit this adhesive to set so as to properly secure theoutsole on the lasted upper, and also to lay and level the out sole onthe lasted upper, it is necessary tr, apply pressure thereto, and tocontinue this pressure until the adhesive has set, when the outsole willbe accurately leveled and effectively secured to the lasted upper.

I apply this pressure preferably by means of an elastic band, this beingpreferable in the form of an elastic fabric webbing, although it is tobe understood that other forms of suitable elastic material may beutilized. The preferred manner of applying this elastic band is perhapsbest illustrated in Fig. 3. One end is tacked or otherwise secured as at5 to the heel portion of the upper and the band is then placed along thetop of the sole as at 6, and then around the edge portion of the balland toe as at 7 and 8 so as to engage both the sole and the upper ofthis part of the shoe. The band is then turned over the bottom of theshoe near the shank as at 9 and brought entirely around the upper as at10-, this spiral being continued and the band wrapped around the toe asat 11, the

wrapping continuing as at 12 and 13 in a spiral manner to the shoe untilthe other end is secured to the last as at 14.

as seen in both Figs. 1 and 2, it is obvious that the elastic bandpractically covers the entire area of the outsole and holds the samewith a yielding pressure, securely against the upper. Due to thisyielding pressure the sole is leveled to the lasted upper so that itconforms exactly to the shape of the last. This pressure is also ofsufficient strength to securely hold the sole to the upper while theadhesive is setting. When this adhesive sets, the elastic band may beremoved and the shoe is complete. The length of time necessary for theadhesive to set, depends upon the characteristics thereof, it beingpreferable, of course, to use a quick setting adhesive in the interestsof expediency.

What I claim is:

1. A method or process of laying and securing soles to uppers, includingproviding a lasted upper, placing an outsole thereon with an adhesivetherebetween, and wrapping an elastic member about the sole and upperbeginning at the heel portion of the upper, extending along the sole andaround the edge of the ball and toe portion of the sole so as to engageboth the sole and upper, then around the entire lasted shoe and over thetoe portion thereof and thence spirally around the lasted shoe to therear end thereof, so as to apply a continuing pressure. 7

2. A method or process of laying and securing soles to uppers, includingproviding a lasted upper, placing an outsole thereon With an adhesivetherebetween and applying a continuing pressure to the sole by means ofa member Wrapped around the sole and upper with portions of said memberextending substantially cross-Wise of the sole and another portionextending substantially lengthwise of the sole.
